How to use batch to convert .dcm to .mat files?

Morning everyone,

I am studying AGE relate to human macromolecules by qMT.

I am just a beginner and trying to run dcm2mat_batch to convert .dcm to .mat for getting T1 maps.

I got a code and open in Matlab but cannot output any .mat file.

Here is the code:

files = dir('*MR*');
filesOrder = {files.name};
D = filesOrder; 

% % organizing files based on the last number
% reg = regexp(filesOrder,'\d+$','match','once');
% [~,idx] = sort(str2double(reg));
% D = filesOrder(idx);

for i = 1:length(D)
    thisfile = D{i};
    dicom = double(dicomread(thisfile));
    % num2str to identify slice, change name of file for your preference
    save([ 'VFA_DATA_FA_14_250ms_sl_' num2str(i) '.mat'], 'dicom');
end

I did try change

files = dir('*MR*');

to.

files = dir('*IM*');

But shows

Error in dcm2mat_batch (line 12)

dicom = double(dicomread(thisfile));

Does anyone can tell me which part I need to changed than this code will work?

Thank you

If MATLAB is able to do the dicomread, but is not able to do the save, then that means you do not have permission to write to the current directory.

My problem is solved, I didn't install Image Processing Toolbox.

After I install Image Processing Toolbox, I can convert dcm2mat batch now.

Thank you for answering that, I am too primitive.

Hi Ti Wu, can you share with me how to convert dcm to mat ?

Yes, I can share with you.

But to clarify the batch owner is not me.

I want to make a clarification.

This batch was made by San DIego State University Graduate Student "John Cameron White".

If he consider this is his patent and don't want to share to anyone.

I will not send it to you.

Give me few days to get his permission.

Then I will send the batch to you.

Use Matlab open it and select folder you want to change then run.

I believe you can make it.

Sincerely

TI WU
